    Hi! I'm interested in developing the software updater for other applications, for example such as in CCleaner or Avast, they have such feature.

    Screenshot:

    enter image description here

    The question is how these apps know about the newest software version available? Is there any kind of the online database for that or software companies share such info with them? Thanks.

      Hi,

      Usually, yes. There's a server that publishes available versions with information.

      You can see the same idea but implemented differently in the Qt online installer for example.

        Hi! So how to get this data from that server (url or docs how to access it)? It is public server? Thank you for the answer.

          That will depend on the framework used. But the two I remember were using an RSS feed that provided the information to be shown by the updater/installer.

            Can you share these RSS feeds, or at least some info how to find it? Thank you.
